We've taken the baseline stock suspension platform of the RZR 900 and bumped up the technology to provide a better tune for trail riding. Extra adjustability is provided in three simple clicks of the compression switch, and the piggyback reservoirs add extra damping for more control. The Performance Series 2.0 Podium quick switch 3 (QS3) front and rear coil over shock kits are designed to be bolt-on ready for the Polaris RZR 900 vehicles with 50 in. - 55 in. widths.
